Awesome! Two skaters before Mura tried to put 4T as a second jump in combo: Menshov 4T-4T www.youtube.com/watch?v=Fx3GnlX4TlY and Plushenko 3A-4T www.youtube.com/watch?v=WBVM8NB27WI . All guys did it UR, but Mura's attemp is probably the best among all. No one ever tried it in competitions. Mura has a wonderful 4T and the most amazing and powerful 3A in Men's history. He is not that stable sometimes but he might wanna try to push this record. As for how much such a 4T-4T combo would cost, that's just easy to find out it: 10.3x2=20.6 ) .
